If you’ve been dreaming of swimming in some of the clearest waters in Thailand, mark your calendar! The Similan Islands, one of the top diving and snorkeling spots in the world, will reopen to travelers from October 15 to May 15 every year. The rest of the year, the park is closed for monsoon season and marine ecosystem recovery — a sign of Thailand’s commitment to eco-tourism and conservation.
🌴 What Makes Similan Islands So Special?
Located in the Andaman Sea, about 70 km off the coast of Phang Nga province, the Similan Islands are a national marine park made up of 11 islands. These islands are a paradise for divers, snorkelers, and nature lovers.
Highlights include:
• World-famous dive sites with vibrant coral reefs
• White sandy beaches that feel like flour under your feet
• Crystal-clear turquoise waters perfect for underwater photography
• Rare marine species like manta rays, whale sharks, and sea turtles
• Guided eco-tours by licensed operators like Muna Tours
Whether you’re on a day trip or overnight liveaboard, visiting Similan is a bucket-list adventure that must be timed just right.
🐢 Why the Seasonal Closure Matters
From May 15 to October 15, the Similan Islands are closed to tourists. This not only protects visitors from rough seas during the monsoon season, but also gives the marine ecosystem time to recover. Coral reefs, fish populations, and nesting turtles benefit greatly from this annual rest.
It’s part of Thailand’s movement toward sustainable travel and responsible tourism, making your future visit even more meaningful.
📅 Best Time to Visit
The best months to explore the Similans are November through March — calm seas, great visibility, and ideal weather for both diving and island-hopping.
